Kevin Costner claims he took morphine while filming ‘Hidden Figures’

The superstar actor sat down for an interview with People released Saturday…and he talked about the 2016 hit film about several black women and their contributions to the space race around the 17-minute mark.

KC – who plays the director of the Space Task Group in the film – says most of the shoot went according to plan… until a kidney stone attack destroyed him.

Costner says he spent the last 10 days on set filming while using an opioid IV for pain relief. The first three days, he says, he was relatively normal… the last seven, not so much.

Costner says he had to roll up his sleeves in the film instead of keeping them rolled up at the elbows as if to hide the needle marks on his arms.

KC says he’s never worked drunk or high – although that’s a little hard to believe considering he used morphine in his trailer. Regardless, he says he hasn’t missed a single day of filming – he’s a tough cowboy, after all.

Of course, “Hidden Figures” – with Taraji P. Henson, Octavia Spencer, Janelle Monáe, Jim Parsons, Glen Powell, Kirsten Dunst, Mahershala Ali and more stars – became a huge success, grossing more than $230 million at the box office.
